ContentEditable execCommand() alternative?

[fluid]

I have a contenteditable div on a page. I know there are a few in-built functions (execCommand()) which i can use but i need to be able to insert H5 tags in the contenteditable. So my question is how do i create a custom execCommand to do the H5 for my page. Or any other alternative?

Maybe I'm misunderstanding what you're asking, but have you tried this?
yourObj.execCommand('formatblock', false, '<h5>')

What i really want to do is <h5 class=myclass>my text</h5>.

I tried yourObj.execCommand('formatblock', false, '<h5 class=myclass>') but it doesnt work. Any ideas?

Alrite, i found solution to this.

Just one little javascript function was enough to do it.

getElementsByTagName()
setAttribute()

thanks anyway torunforever
